In the development process of modern industry, the problem of bubbles is a challenge that cannot be ignored. The existence of foam will not only have a negative impact on the production efficiency, quality and progress of industrial products, but also may cause pollution to the external environment, and then affect the natural environment of human survival. Foam problems will occur in many industries, such as water treatment, industrial cleaning, coatings, textiles, printing and dyeing and other industries, and the occurrence of foam cannot be avoided. In order to be able to better eliminate the foam generated in these industries and avoid the impact of foam on industrial development, it is necessary to find a suitable defoaming method, and we will find out todayTextile defoamers
Textile defoamer application scenario diagram).
In the textile printing and dyeing process, foam problem is a common phenomenon. There are two main reasons for this: first, a variety of surfactants need to be added in the production process; Secondly, the formation of foam is caused by the high-speed movement of dyes and yarns, as well as the repeated movements of machinery. In addition, the addition of textile printing and dyeing auxiliaries will also cause a large amount of foam to be produced in the dyeing pool due to stirring and mechanical shaking during slurrying.
The effect of the presence of foam on textiles is manifold. First of all, a large amount of foam is not treated in time, which will produce white spots and spots on the fabric, destroy the color uniformity of the fabric, and affect the quality and beauty of the clothing. Secondly, too much foam will also directly affect the performance and quality of textiles. The foam problem may also cause pollution to the external environment, which in turn affects the natural environment on which human beings depend. Therefore, it is very important to effectively control the foam problem in the textile printing and dyeing process.
Textile defoamersHigh content, good water solubility, no oil bleaching, strong acid and alkali resistance, high temperature resistance 60-135, can show excellent foam inhibition and good defoaming in non-ionic and anionic surfactant systems, and can quickly defoam and inhibit foam for a long time under medium and high temperature strong alkali conditions. It has good defoaming and foaming inhibition properties, and is used in chemical cleaning with high alkalinity, and has a much longer foaming time than ordinary silicone defoamers.
